Schematic illustration of the synthesis of Ni NWs. a, b The process to synthesize CM-NWs. c, d The process to synthesize DM-NWs. In the figure, the yellow spots represent the Ni nanoparticles, the dashed lines represent the magnetic induction line, and the drop-shaped area bounded by the dotted line indicates the diffusion region of the NiCl2·6H2O solution followed by the reaction time
